Jessica Alba hits gym six weeks after giving birth

Jessica Alba has hit the gym just six weeks after giving birth to her son Hayes.

The 'Sin City' star - who is also mother to daughters Honor, nine, and Haven, six, with husband Cash Warren - welcomed third child into the world on December 31, and on Monday (12.02.18), Jessica shared a selfie of her dripping in sweat with her personal trainer after doing an intense static cycling class.

The 36-year-old actress recently revealed she has been using her maternity leave to catch-up on her favourite box sets.

And it seems she has become addicted to Netflix comedy 'Grace and Frankie' whilst at home with her kids.

Jessica shared a picture of herself snuggled up to newborn on Instagram and wrote: "Tuesdays/all the days w my Hayes #chillin watching @graceandfrankie-I'm on season 4 and I don't want it to end ? #bingewatching #graceandfrankie#lovethisshow #newbornmom (sic)"
